Sutton, Rockford, Ill., assignor to The Brearley Compan Rockford, Ill., a corporation of Illinois Application June 21, 1937, Serial No. 149,394 19 Claims. (Cl. 265-68) This invention relates to weighing scales, and being arranged to be inverted and set down over has particular reference to one especially dethe base and detachably connected therewith in signed for bathroom use. a novel manner, whereby the assembling of the Bathroom scales have generally been subject to scale is greatly simplified and the scale may be 5 the objection that they are not easy to read. produced at 10W cost.

An elongated Vdle thereof with the rack platform, as at I6. The forwardly reaching arm 25 of the lever I4 is connected with the lower end of a coiled spring 26 which resists movement thereof, and the movement of this arm 25 results in the operation of the indicating mechanism, as will soon appear. As the platform 8 is brought down into position over the base IU, three small sheet metalY lugsv 21 welded or otherwisesuitably secured to they inside'I of the sideV walls 8 of the platform have the inclined bottom edges 28 thereof arranged to deflect 29 that are welded or otherwise suitably secured in the base IIJ in register with these lugs 2'I-.

The tongues 29 will deflect, as indicated in dotted lines in Fig. 2, a certain distance until lugs 2.1- come into register with vertical slots provided in the tongues, whereupon there is sucient spring-back of the tongues to interlock the scale` Then, if desired, thetongues:

platform and base. can be reached through the space between the outside ofthe base andl the lower edge of the platform side walls to forcibly bendthese tongues outwardly back'to vertical position as they ap` pear in fullV lines in Fig. 2. One can thereafter lift the scale by means of the platform without danger of the base dropping off.

Referring now to Figs. 2v and 4 to 6, a plate 3l having an upwardly bent circumferential flange 32' telescoping linside the dial housing II has a rectangular opening 33 therein and two downwardly bent lugs 34 on opposite sides of said opening. The platform 8 has a registering rectangular opening therein defined by a downwardly bent flange 35 adjacent which the lugs 34 on the plate 3-IV are disposed' when the plate is fastened to the platformby screws 36, clamping the mat I3 therebetween. Bearing brackets 3l which are preferably riveted to the plate 3l, as at 38, have the screws 36 entered. therethrough, and they provide hangers '39 adjacent the lugs 34, previously mentioned, for bearing support of the dial shaft 48 while the latter is held byv engagement with the lugs 34 against endwise movement, or is at least limited in its endwise movepinion 4I on the engagement at the mid- 42, but has its opposite ends extended through thimbles 43 constituting supporting hubs on a pair ofv dialsv 44- and 45. The protruding ends of the shaft'48 at the ends of the pinion 4I extend through center holes in the dials, and in that way the two dials are supported on the shaft andpinion in parallel concentric relation side by side with. their annular flanges 46 extending inwardly toward one another but spaced sufficiently to receive the rack 42 and its guide 41 therebetween, as well as the channel-shaped sheet metal extension piece 48 on the arm 25 for operating the rack 42. The extension piece 48 is disposed with the web thereof on the bottom and it carries a crosspi'n 48 on the rear end thereof for attachment of the -hook of spring 26 thereon, and the arm 25,` previously mentioned, fits. in the rear end of the piece 48 between the side walls thereof and is arranged tobe clamped in place by bending over lugs 58 provided on the upper edge of the sidewalls of the piece. Since the web of the piece 48 is on the bottom, the lower end of the rack 42 can t in the channel'of the piece 48, as clearly appears in dotted lines at 5I in Fig. 2.l A vertical lug 52 'bent inwardly from the side wall 8 of the platform 8 at the front end thereofprojects into the forked front end 53 of the extension piece 48 to limitthe side play of shaft 48 has meshing sheet metal tongues the member in operation and prevent the same from coming in contact with either of the dials 44 and 45. The front end of the extension piece 48 is made forked by simply cutting away the web from between the side walls of the channel, as at 54. A downward extension II' on the front end of the dial housing II covers the opening formed;v wherefthe lug 52 isbentinwardly, and a screw I I" serves tofasten the dialfhousing down, this screw being Aentered through a hole in the extension II' and threaded in the wall 9 of the scale platform.

'I-heguide 4l is formed by two pieces of sheet metalv 55. of. the general form appearing in side view inFig. 2.andtop`view in Fig. 5. These pieces are disposed in: a, vertical plane and riveted or otherwise secured together, as indicated at 5B. The guide bracket thus formed is supported at the. front end on the plate 3| by slotting the end of the bracket, as at 51, and entering a portion of the plate next to the opening 33'V therein. The rear end of the bracket is formed into a fork 58 by bending the pieces 55 apart, as clearly appears in 5, and this fork rests on: top. of the plate 3-I and isclamped to the plateby a. U-shaped sheet metalyoke 59E that fits over the fork 58 and is fastened to theplatform 8 along with the plate 3I byrneansofscrews 6U. The yoke 59 provides a mounting for the knurledv adjusting nut 6I which is threaded on a screw 52: attached tothe upper end of the spring: 26. The nut 6I projects through a slot 631 in the rea-r end of the dial housing I-Iv for manual' adjustment. TheV guide bracket 4l has its pieces: 55 bent apart intermediate the endsthereof to form a vertical guide 64. in which theV rack 4-2 operates up and down. Rounded knobs 8.5- are struck inwardly from the side walls of the guide 8'4 to. lightly engage the opposite sides of the rack 42 soz as to hold it in spaced relation to the side walls of the guide to operate as smoothly and as. easily as possible. A few crosspins B6 extend cross-wise through the guide 64 lightly engage the smooth back of the rack 42 andy guide it for straight line. vertical motion in proper meshing engagement with the pinion4l. at all times, while still avoiding undue frictional drag upon the movement; of the rack. The point contact at 5I between the lower end.- of the rack and the extension piece 48 on the lever I4 also makes for minimum resistance to movement. It should be apparent, therefore, that the rack 42 is free to gravitate downwardly when the lever I4 is deflected downwardly under the weight of a person standing on the platform 8. The deflection of the spring 26, of course, counterbalances the weight imposed on the platform, and its counterbalancing force is determined by the longitudinal adjustment of the extension piece 48 because that adjustment shifts the pin 49 in a fore and aft direction and accordingly decreases or increases the mechanical advantage of the spring with rela- Vtion to the lever I4. The lugs 58 are bent into tight engagement with the arm 25 when the proper adjustment has been made. Obviously the dials 44 and 45 turn in a clockwise direction, as viewed in Fig. 2, when the rack 42 gravitates from a position of Zero weight indication to some other position when a person stands on the platform. The fact that the dails themselvesare accurately positioned in the manner shown in Fig. 4 and the rack 42 is accurately guided, as best appears in Fig. 5, eliminates any danger of the parts rubbing on one another and destroying the accuracy of weighing. The provision of two dials in laterally spaced relation, symmetrically l which the hair line 'I4 of the light bulb vented from doing so arranged with respect to the rack and pinion, also makes for a well balanced construction, the rack engaging the pinion at the exact middle, half way between the two dials, and the inertia of the dials to either side of this point being the same.

The tops of the dials 44 and 45 are visible through a window 61 in the top of the dial housing Il. A hair line 68 extending diametrically of the window transversely with respect to the front end of the scale serves as a pointer or index mark to cooperate with the graduations 69 on the dials 44 and 45. The latter are in broken columns on the two dials, ten pounds being marked off in groups with blank spaces between, and the graduations being in staggered relation on the two dials so that the graduations on one dial occur opposite the blank spaces on the other, as clearly appears in Fig. 5. This feature plus the provision of large easily legible numerals at ten-pound intervals, 0, l0, 20, 30, etc., makes for easy reading by avoiding the blur effect produced where there is a solid column of closely spaced graduations. The graduations themselves are for two pounds and one pound so that when a person stands on the scale platform he has no difficulty in reading his weight to within a pound; he simply notes the large numeral nearest the hair line 68 and to the front of it and then according to the point at 68 crosses the graduations behind this large numeral he can quickly tell his weight, it being at once apparent what the weight is in round numbers, and then upon closer inspection, the exact weight within a pound is determined by the hair line. The hair line 68 and the wide band crossing it at right angles are both preferably of vitreous enamel red into the glass on the under side. The band 10 covers up the space between the dials 44 and 45 so that nothing shows but the dial graduations. This band, as

' will now appear, also acts as a deflector or shield over the electric light bulb 1| to conceal the light bulb from view and at the same time shed the light over the dials and avoid any glare being transmitted through the window 61 when the light is turned on.

The light bulb 1| is mounted in an opening in a piece of insulating material 12 riveted or otherwise secured on an arm 13 carried on one side of the guide bracket 41. 'Ihe threaded butt makes grounding contact at 15 with the arm 13. A switch terminal 16 makes contact with the other terminal 11 of the bulb and is fastened to the insulation member 12, as indicated at 18. It has an upwardly bent end 19 arranged to make contact with the leaf spring switch blade 80 that is fastened to the insulation member 12 at one end, as at 8|, and tends normally to spring downwardly into engagement with the terminal 16 at 19, but is normally preby the rack 42 which engages a button 82 of insulation material carried on the free end of the switch blade 80, holding the blade 88 out of contact with the end 19 of the terminal. It is obvious from this description that if the dry cell battery 83 has its one terminal grounded and its other terminal connected with the blade 80 that the bulb 1| will be lighted when the rack 42 gravitates downwardly in rev sponse to movement of the lever YI4 under weight imposed on the scale platform, at which time the switch blade 8!) contacts the end 19 of the terminal 16. The lighting of the scale is therefore entirely automatic and the light ilashes on only so long as someone is standing on the platform;

l as soon as the weight is removed from the scale platform so that the rack 42 can return to its normal position as shown in Fig. 2, the blade 80 is moved out of contact with the end 19 of the terminal 16, and the light circuit is broken. The spring 80 cannot aifect the accuracy of weighing, even though it does exert light pressure on the upper end of the rack 42 when the scale is at rest and there is no weight on the platform, because the rack 42 moves out of engagement with the button 82 on the spring 80 almost the instant weight is applied to the scale platform.

The dry cell battery 83 is mounted in a coiled spring holster 84 which serves not only to support the cell resiliently so that it will not be affected by shock and jar incident to shipment of the scale or rough usage, but it also serves two other important functions, namely, (1) to hold the cell under constant thrust upwardly to insure good contact of its center terminal 85 with the metal cap or closure 86 by which the battery is grounded to the scale platform 8, and (2) to provide a means for automatically expelling the burned out cell when the closure 86 is removed, whereby to permit easily replacing the cell. The upper end of the coiled spring 84 is bent into a large flat coil 81 that is fastened to the scale platform 8 by lugs 88 struck from the sheet metal of the platform. The lower end of the spring 84 is wound spirally in a flat plane, as at 89, to close the bottom of the holster, and a terminal 90 insulated from the spring by a button 9i of insulating material is fastened to the end of the spring at the center of the bottom of the holster. The cell 83 has the usual insulating jacket covering the sides thereof, but the terminal 90 makes contact With the exposed metal bottom of the metal casing forming the other terminal of the cell. The same results are obtained when the cell is inserted upside down, because terminal 85 then touches button 90 and the metal bottom of the cell touches the closure 88. A flexible insulation covered wire 92 connected with the terminal 98 is connected with the switch blade 8D at its remote end, as at 93. The closure 86 fits in an opening 94 provided in the top wall of the scale platform 8. A marginal flange 95 on the closure rests on top of the mat I3 on the platform alongside the opening and there is a lug 96 on one side of the closure arranged to engage under the top wall of the platform at one side of the opening, and a spring latch 91 on the diametrically opposite side of the closure arranged to engage under the top wall of the platform on that side of the opening 94, whereby to retain the closure in place securely but still permit easy removal thereof. A small tab 98 projects above the platform and is integral with the latch 91 and may be engaged by a finger nail or by any instrument entered under it to move the latch 91 out of engagement with the wall of the platform next to the opening 94 so as to permit removal of the closure. As a matter of fact, the closure will spring upwardly like the lid of a jack in the box when the latch is released, because the cell 83 under pressure of the spring holster 84 keeps the lid under constant tension toward upward movement. Obviously, when the lid springs up, the cell 83 rises to approximately the dotted line position shown in Fig. 3, and it can therefore be removed readily. With any other arrangement for housing the dry cell battery some other precaution would have to be taken to faciiitate withdrawal of the used cell, or else it would be necessary to turn the scale upside down to get the Aso cell out. The spring holster 84 solves the problem in a very convenient lmanner and in addition affords the other advantages previously mentioned with regard to a resilient shock absorbing mounting and one which insures good electrical contact at the two points 85-86 and 96. Furthermore, the present construction is lighter than'others proposed and also reasonably economical and easy to assemble.

It is believed the foregoing description conveys a good understanding of. the objects and advantages of my invention. The appended claims have been drawn with a view to covering all legitimate modications and adaptations.
